Below is the example of Array reverse() method.
-
Example:
<script>functionfunc() {// Original Arrayvararr = ['Portal','Science','Computer','GeeksforGeeks'];document.write(arr);// Reversed arrayvarnew_arr = arr.reverse();document.write("<br>");document.write(new_arr);}func();</script> -
Output:

The arr.reverse() method is used for in-place reversal of the array. The first element of the array becomes the last element and vice versa.
Syntax:
arr.reverse()
Parameters: This method does not accept any parameter
Return value: This method returns the reference of the reversed original array.
Below examples illustrate the JavaScript Array reverse() method:
-
Example 1: In this example the reverse() method reverses the sequence of the array elements of arr.
var arr = [34, 234, 567, 4]; print(arr); var new_arr = arr.reverse(); print(new_arr);
Output:
34, 234, 567, 4 4, 567, 234, 34
Code for the above method is provided below:
Program 1:
<script> function func() {
// Original Array
var arr = [34, 234, 567, 4];
document.write(arr);
// Reversed array
var new_arr = arr.reverse();
document.write("<br>");
document.write(new_arr);
} func(); </script> |
Output:
34, 234, 567, 4 4, 567, 234, 34
